I've not used T2i or any of the Rebel series very extensively, but can compare 50D with 60D/7D, which share some feature with T2i/T3i.
50D has just a little less resolution... Not enough difference you'd notice most of the time. 15MP vs 18MP. By default, 50D images seem a little more "natural", while 60D/7D (and by extension T2i/T3i) seem to render a more "punchy" image. Of course, either can be dialed up or down as you see fit, in post processing or by changing settings in the camera.
50D uses the same Digic 4 processor that's in 5DII, 7D, T2i, 60D, T3i. And all are 14 bit cameras (you have to go back to 30D and 5D classic, to find 12 bit RAW files).
Yes, all 9 points in 40D/50D/60D are cross type. It's perfectly capable of handling fast moving subjects and situations... noticeably better than 5DII, even. Probably better than the Rebel series, too... though I haven't used any of them enough to say from experience... since the Rebels have only one cross-type AF point, at the center, same as 5DII. The center AF point on 40/50/60D is even more sensitive, still the best to use if possible.
Another difference, 40D/50D/60D all have a true pentaprism, while the Rebels use a penta-mirror that makes the viewfinder smaller and a little less bright. 7D's viewfinder is the best of the bunch (5DII's or 1D series is even better), but the 50D's or 60D's would be a nice step up from the Rebel's. You won't notice the difference between pentaprism and penta-mirror much until you are shooting in low light situations. The lens' max aperture also is a factor, so you'd have to use the same lens on each.
For me, 50D's micro focus adjust is important and it's lack on the 60D is one reason I'm not very likely to use that model. I really can't believe Canon omitted MA on the 60D. That was dumb. 40D and earlier don't have MA, either. Among the 1.6X cameras, only the 50D and 7D have had it.
50D uses a 35 zone metering system, same as 5DII/5D classic and earlier xxD models, compared with the newer 63 zone (iFCL or somthing like that, Canon calls it) used in T2i, T3i, 60D and 7D. You won't see any significant differences in most situations, though I do think the new system handles strongly backlit situations a little better.
The xxD cameras controls allow for faster settings changes, and with practice it can be done without removing the camera from your eye.
The joystick also allows for fast changes in AF point selection, without removing your eye from the viewfinder. If you use a grip and shoot vertically a lot, the joystick on the 50D (et al) isn't as easily reached with your thumb. The 60D's new multi-controller is likely better placed in this respect, but would require a joystick user to get used to the new type of controller.
The LP-E6 batteries in the 60D (and 7D, 5DII) are good for about 50% more shots, compared to the BP511A used in the 50D. And better info is available on battery condition, in the camera's menu. However, LP-E6 are also considerably more expensive, when you consider that clone/third party BP511A are widely and cheaply available. Costs have come down on LP-E6, and there are now pretty comparable third party available at a bit less cost (but you have to be careful they are compatible with Canon charger and the camera's battery condition readout system).
I haven't used the smaller LP-E8 that are used in the T2i enough to know for certain, but would guess that the shots per charge are close to the same with BP511A, while shots per charge of LP-E6 would be noticeably greater.
50D uses Compact Flash, which I personally prefer over the SD memory cards used in the recent Rebel models and 60D. I just have nightmares about losing the smaller cards or letting them go through the laundry in a jeans pocket!
I don't have any idea what was up with your 30mm lens on the 40D. Though I haven't use that particular lens, I've used a wide variety of other lenses on a series of Canon models, really only see any of them "bog down" noticeably on 5DII (which has an AF system more similar to the Rebel series, than to the xxD series.... though it's not really same as the Rebel either... 5D series actually has hidden "Assist/Expansion" points to try and help AI Servo work better).
If you use back button focusing and
BG-E2/E2N battery grip that fits 50D (actually 40/30/20D too), you have to assign the BBF to the * button and live without easy access to AE Lock. This is because the battery grip doesn't have the AF On button. It's not really a big deal... I still swap the buttons on my 5DII and 7D, because the * is closer and larger and I prefer to use it for back button focusing.
50D has user interchangeable focus screens. I use the grid or "D" type in mine... also in 5DII. 60D, 40D, 30D all use the same screens. Not sure if the 20D does too. (Note: I guess it's possible to fit third party focus screens to the Rebel series, such as Katzeye Optics, but it's more involved to change them out, not designed for an easy switch.) 7D instead has that fancy "active matrix" screen, with grid on demand and that reconfigures the AF point array depending upon what you have set. I guess the new 1DX is going to have something similar to the 7D's, as well as some (all?) of the 7D's unique focus modes.
50D is a more durable camera. Shutter is rated to 100K, compared to 75K with most Rebel (some older or more entry level might be only 50K). 60D is also 100K, while 5DII and 7D are rated for 150K. Of course, these are just estimates of durability, not a guarantee. 50D has a metal chassis and is metal clad, while I think all Rebel are plastic over plastic, and 60D has metal chassis but is mostly plastic clad.
Speaking of the shutter, 40/50/60D offer 1/8000, while I don't believe the Rebel series go over 1/4000. Also, flash sync on xxD is 1/250... It's 1/200 on the Rebel series (and on 5D series, due to the larger shutter no doubt). Note that most studio strobe require slightly lower sync speed. And, most of these cameras can be used with High Speed Sync flash (Canon and perhaps some others), that allows much faster shtuter speeds but seriously limits flash distance.
No video with 50D.
And it doesn't have the built-in wireless flash control of some of the later models. However it can be fitted with ST-E2, which in a few respects might be better than the built-in wireless flash control. (It doesn't overheat as easily and doesn't rely upon visible light flashes to communicate with the remote flash... and it can provide IR focus assist in low light situations.)
I never had any trouble setting Custom White balance with 50D. I have yet to meet a Canon model that I think does very well with indoor tungsten or "warm white" compact fluorescent lighting. IMO, they all render it too yellow. Common household CFL, in particular, are poorly balanced and there's a lot of color variation from one brand to another... plus they flicker at a high rate, which can mess with exposure and WB. I use Lastolite white balance targets and like the results I get in a variety of types of light.
